Perhaps best known as the co-creator of "The Office" and "Extras," and for his comedic roles in "Hot Fuzz," "Life's Too Short" and, yes, "Extras," the 6-foot-7 Merchant her plays the Marvel Comics mutant who can sense and track other mutants. In the James Mangold film, Caliban helps Hugh Jackman's Logan care for the ailing Charles Xavier (Patrick Stewart).

“I’m always interested to find the thing that looks most interesting on the actors," Mangold explained. "Stephen is a huge man. One of the things that is so wonderful filming with him for a character like this is that he’s a good six inches taller than Logan, and huge over Patrick. The little kid in the movie would come up to basically his knee. So there’s a wonderful sense of scale – but he has heart too. So that was a wonderful energy to enter the movie, and someone who instead of turning things into their own energy kind of joined ours.”

Jackman's ninth, and purportedly final, appearance as Wolverine, the film is set years after the epilogue of 2014's "X-Men: Days of Future Past." His healing factor failing, a weary Logan cares for an ailing Professor X in a hideout on the Mexican border. But his attempts to hide from the world and his legacy are up-ended when a young mutant arrives, pursued by dark forces.

Opening March 3, “Logan” also stars Richard E. Grant, Boyd Holbrook, Dafne Keen, Eriq La Salle, Elise Neal and Elizabeth Rodriguez.
